Runtime reconfigurable architectures based on Field-Programmable Gate Arrays (FPGAs) are attractive for realizing complex applications. However, being manufactured in latest semiconductor process technologies, FPGAs are increasingly prone to aging effects, which reduce the reliability of such systems and must be tackled by aging mitigation and application of fault tolerance techniques. This paper presents module diversification, a novel design method that creates different configurations for runtime reconfigurable modules. The authors' method provides fault tolerance by creating the minimal number of configurations such that for any faulty Configurable Logic Block (CLB) there is at least one configuration that does not use that CLB.
